Exercise 23 Page 78

What do m and b represent in y=mx+b?

Equation: y=3/2x+7/2
Slope: 3/2
y' -intercept:' 7/2

Practice makes perfect
Equations in slope-intercept form follow a specific format, where m represents the slope of the line and b is the y-intercept. y= mx+ bLet's rewrite our equation a little bit so that it more closely resembles this format. This will make it easier to identify the features of the equation.
-3x+2y=7
2y=7+3x
y=7+3x/2
y=7/2+3x/2
y=3x/2+7/2
y=3/2x+7/2
Below we have highlighted the slope m and y-intercept b. y= 3/2x+ 7/2 We can see that the slope is 32 and the y-intercept is 72.
